Our exclusive Keychron Super switch adopts a new mold with unparalleled precision. Every switch is tested for pro-grade quality and has a lifespan of up to 50 million clicks, providing great reliability and high performance for long typing sessions. Its new light affection structure on its transparent top housing also ensures high light transmittance and a more consistent, brighter backlight effect.

To further fine-tune your typing experience, the K2 Max comes with our unique OSA profile (OEM profile with spherical-angle) and double-shot PBT keycaps that aim to provide a more comfortable fingertip feel with excellent oil resistance for long-term use on the 75% layout.

Even a small part matters for your fingertip feel. We’ve integrated the PCB-mounted screw-in stabilizers for a smoother typing experience with less wobbliness on the big keys such as space bar, shift, enter, and delete. The Keychron K2 Max also supports third-party screw-in PCB stabilizers.

Three levels of adjustable typing angle (5º, 9º & 12º) and curved OSA-profile keycaps are all working together to provide long-lasting ergonomic support for your wrist.
